This invention relates to new and useful improvements in oildistributing systems and aims tof rovide a system whereby oil from theusua gas trap will be properly distributed amongst a large number-of 011tanks arranged at various places in an oil field.

More specifically, the system aims to control the suppl of the oilfromthe gas trap to the oil tan s so that all of the oil tanks will atonce be filled to maintain a relatively constantlevel, the. systemincluding general-' ly a gravity line leading to all of the oil tanksand having communication with the gas trap, a valve structure beingarranged between each oil tank and the gravity line that is auto-.matically operable to open position when the oil drops below a certainlevel and that is automatically closed when the oil reaches apredetermined level, the valve being so con- 2 structed. that when thesupply of the oil to aparticular tank is closed, the gravity line willbe opened to the next adjacent tank and so on throughout all of thetanks in the field.

A most important object of this invention is to provide a system of thischaracter that is of unusually simple construction, but at the sainetime positive and automatic in its operation so as to maintain apredetermined level of; the oil within all of the oil tanks which aresupplied from the usual gas trap receiving its supply direct from theoil well.-

With the foregoing and other objects in view as the nature of theinvention will be better understood, the same comprises the novel form,combination and arrangement of parts hereinafter more fully described,shown in the accompanying drawings and claimed.

In the accompanying drawings wherein like reference characters indicatecorresponding parts throughout the several views:

Figure 1 is a top plan view disclosing frag- 1 mentarily a conventionalgas trap, and two 'storage tanks within afield, said tanks and gas trapbeing equipped with our improved system.

Figure 2 is a plan view of a valve stem guide spider.

Figure 3 is a side elevation partially in cross section of the gas trapand oil tanks, the

60 present system being installed, the tank near- 'est the gas trapbeing filled and the flow of the oil therein cut of]? by reason of theimproved valve while the next tank is illustrated as receiving itssupply of oil from the gas trap.

Figure 4 is a detail longitudinal section of the valve structure per se.

Figure 5 is a horizontal section taken substaitially upon the line 5-5of Figure 4, an

Figure 6 is a horizontal section taken substantially upon the line 6-6of said Figure 4 and looking downwardly in the directionof the arrow.

Now having particular reference to the drawings, and-especially toFigures 1 and 3, A designates a conventional gas trap within an oilfield that receives its supply of oil direct from the well, while B andC designate two of the usually large number of storage oil tanksarranged throughout the field and receiving their supply of oil fromsaid gas trap.-

Our invention per se consists of a gravity oil supply line 5 havingcommunication at one end with the gas trap A and having communicationwith all of the oil storage tanks within the field through the medium ofa valve structure arranged within the deck of each tank, this valvestructure being designated generally by the reference character 6.

Each valve 6 consists of a somewhat elongated cylindrical body 7constructed to provide an upper and a lower chamber 8 and 9, thesechambers communicating through a renewable valve seat ring 10. Havingcommunication with the lower chamber 9 directly beneath the upperchamber is an inlet nipple 11, while corrnnunicating with the upperchamber 8 is an outlet nipple 12, these nipples being constructed in anysuitable manner to permit the arrangement of the valve within thegravity line 5, see Figures 1 and 3.

The opposite ends of the body 7 are open while arranged within the,upper open end is a suitable closure 13.

Longitudinally slidable through this closure 13 and through a removablespider 14 within the lower end of the body 7 is a valve stem 15 that isalso movable through the center of a renewable valve seat ring 16 withinthe lower bod chamber 9 and above said spider 14 as clear y disposed inFigure 4. Between the valve rings 10 and 16 the valve stem 15 isequipped with a pair of spaced valve plugs 10' and 16' constructedcomplemental to said valve seat rings.

The lower end of the body 7 is with a longitudinal slot 17 extendmhorizontally through which and pivoted a jacent its inner end within theb0 the inner end of which terminating directly beneath the lower end ofthe valve stem 15 and being e nipped with a reglulating set screw 19. Te outer end of t is'lever is formed with a goose neck upon which isadjustably arranged a suitable float member 20. Surrounding the valvestem 15 between the uppermost valve plug 10' and the closure 13 is anexpansible counterbalancing spring 21, the strength of which is sli htlyless than the weight of the outer end 0 the lever 18 and the float 20 sothat when the-outer end of the lever is in horizontal position the saidstem 15 will be forced upwardly against the action of the spring 21 soas to maintain the plug 10 within its seat cutting off the passage ofthe oil into the but permitting the oil to ow through the lowermostchamber 9 into the respective storage tanks of the valveunit, the lowerend of the valve unit being suitably arranged in oil tight mannerthrough the deck of the tank as disclosed in Figure 3. However, as

soon as the oil in this tank reaches the float 20, the outer end of thelever will be swung upwardly, releasing the pressure against the valvestem 15 whereupon the stem will be forced downwardly by reason of thespring 21 for closing the passage to the lowermost chamber and openingthe passage to the uppermost chamber so that the supply of oil to theparticular tank will be cut ofi but opening the supply of oil throughthe gravity line to the next adjacent tank, the operation beinggolligipleted throughout all of the tanks in the The said gravity line 5at opposite sides of each of the valve units 6 is equipped with cut oilvalves 2121 to permit installation of the stem, the draining of any ofthe tanks and also the supply of oil into any predetermined tanks.

Communicating with all of the storage tanks in the system is the usualoil line 22 whereby the oil may be conveyed from any desired one orplurality of the storage tanks.

In view of the foregoing description when considered in conjunction withthe accompanying drawings it will be apparent that through an oildistributing system of this character the various oil tanks within anoilfield may be automatically filled as soon as the oil level therein dropsbelow a predetermined degree so that a relatively constant rovided I yis a lever 18,

igiper chamber 8,

level will be maintained at all times within a the various tanks.

Even though we have herein shown and described our improved oildistributing system as consisting of certain detail structural 'featuresit is nevertheless to be understood that some changes may be madevtherein without affecting the spirit and scope of the appended claim.

Having thus described the invention, what valve stem arranged forslidable movement centrally through said chambers,-the upper and lowervalves secured on said stem for cooperation with the inlet and outletopenings of the upper and lower chambers respectively, float operatedmeans associated with the lower end of the cylindrical body andcooperating with the lower end of the valve stem for raising the same tounseat the lower valve and seat the upper valve during the filling ofthe receptacle, and additional means for moving the valve stemdownwardly to close the outlet opening in the lower chamber and open theinlet opening in the upper chamber when a predetermined level is reachedin the receptacle, said float control means including a lever pivotallysupported at its inner end on the lower end portion of the cylindricalbody and adapted for vertical swinging movement, a float carried b theouter end of the vertically swinging ever, the ivoted inner end of thelever terminating irectly below the lower end of the valve stem forcooperation therewith, and a regulating set screw arranged verticallythrough the inner end of the pivoted lever for engagement with the lowerend of the valve stem.

In testimony whereof we aflix our signatures.
